Rebeico Project, Sonora, Mexico
Vancouver, British Columbia--(Newsfile Corp. - July 15, 2020) - Ridgestone Mining Inc. (
TSXV: RMI
)
(
OTCQB: RIGMF
) (
FSE: 4U5
) ("Ridgestone") is pleased to report the first three holes from a recently
completed 1,674 metre drill program on its wholly-owned Rebeico gold-copper project in Sonora,
Mexico. The holes were part of a maiden drill program conducted on the New Year Zone to investigate
the subsurface extent of significant gold and copper mineralization previously sampled on surface.
Highlights
Hole 20REB013D intersected 2.13 g/t gold and 1.79% copper over a 16.25 metre interval
from 3.05 metres to 19.30 metres, including a higher-grade 4.35 metre interval @ 5.25 g/t
gold and 1.46% copper.
Copper mineralization in hole 20REB013D commenced from surface for 19.3 meters
averaging 1.56 % copper.
Holes 20REB014D and 20REB015D collared 60 metres west and about 10 metres south
of 20REB13D encountered significant copper mineralization from near surface to 18
metres.
Pervasively hydrothermally altered rocks with variable amounts of pyrite, magnetite, and
chalcopyrite were encountered in all three of these holes.
Mr. Jonathan George, CEO, commented "We are very pleased that all three of these holes intersected
multiple runs of elevated copper and visible chalcopyrite over tens of metres of length down-hole from the
reported, near-surface significant results.
As well, extensive intercepts with veinlets containing variable
mixtures of pyrite, chalcopyrite, magnetite, chlorite, calcite and quartz, and the intercepts of hydrothermal
breccia, taken together confirm we have penetrated a highly-prospective copper and gold bearing
mineral system."
Hole 20REB13D was drilled vertically to a depth of 98 metres (Table 1), encountering abundant iron and
copper oxides and sulphides in veinlets and disseminations in brecciated and silicified andesite and
hydrothermal breccia from surface to greater than 19 metres (Figure 1 and Figure 2).
Narrower intervals
of hydrothermal breccia were penetrated to depths of 68 metres.
Pyrite and minor amounts of
chalcopyrite ± magnetite were observed in more extensive intervals in veinlets and as disseminated
grains, as well as in narrow veins with calcite and/or quartz.

Holes 20REB014D and 20REB015D were collared approximately 60 metres west and 10 metres south
of 20REB13D (Figure 3) and drilled vertically and west at -55 degrees, respectively. Hole 20REB014D
was drilled to depth of 170.10 metres and intersected 16.2 metres grading 0.25 % copper from 1.6 to
17.8 meters (Table 1). Hole 20REB15D was drilled to a depth of 167.20 metres and intersected 10.90
metres at a grade of 0.19% copper from 1.80 meters to 12.70 metres (Table 1). Both of these
mineralized intervals were within brecciated andesite.
Multiple zones of hydrothermal breccia were
intersected in 20REB014D from 100 to 155 metres, and both holes intersected multiple intervals with
veinlets and disseminated grains of sulphides as well as anomalous gold and copper values at various
depths.

The New Year Zone diamond-drill core program was completed by Layne de Mexico under the guidance
of Steve Weiss (Chief Technical Advisor) and Jonathan George (CEO), with onsite supervision by
geologists from Ridgestone's partner YQ Gold. Drill core of HQ size was recovered by conventional
wireline methods and was transported daily from the drill sites to a secure logging and sample storage
area.
After logging by geologists, intervals selected for sampling were sawed in half lengthwise. The ½-core
samples were placed in pre-numbered sample bags and weighed. Blanks and certified reference
material samples were inserted into the sample stream for Quality Assurance / Quality Control
("QA/QC") purposes.
The samples were transported by YQ Gold personnel to the ALS Chemex ("ALS")
preparation laboratory in Hermosillo, Sonora.
At ALS the samples were crushed in their entirety to 70%
less than 2 mm, then riffle split to obtain a 250 gram sub-sample that was pulverized to > 85% passing
75 microns.
After preparation, the sample pulps were air-freighted by ALS to their assay laboratory in
North Vancouver, British Columbia.
All samples were analyzed for gold by 30-gram fire assay with an
atomic absorption ("AA") finish (ALS method code AuAA23).
The samples were also analyzed for
multiple minor and trace elements by inductively-coupled plasma-emission mass-spectrometry ("ICP-
MS") following a 4-acid digestion (ALS method code ME-MS61).
